ADJUSTABLE ALLIGATR-WRENCH.

To all whom t may concern:

Be it known that I, FRANK W. R-HINES, a citizen of United States, residing at Lamont, in the county of Buchanan, State of Iowa, have invented certain new and useful Improvements in Adjustable Alligatorl-Vrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wrenches and is directed more particularly to a wrench of the alligator type.

An object of the present invention resides in the provision of an adjustable alligator wrench embodying an improved and simplified construction of aw and handle mounting. 4

With the above a-nd other objects of similar nature in view, the invention consists in the construction, combination and arrangement of parts, set forth in and falling within the scope of the appended claims.

In the drawing Figure 1 is a side elevationof a wrench constructed in accordance with the invention,

Fig. 2 is a longitudinal section therethrough illustrating an adjustment of the jaws, and

Fig. 3 is a transverse section taken o-n the line 3 3 of Fig. 2.

Referring now more particularly -to the accompanying drawing, there is shown a wrench consisting of a substantially H-shaped block including spaced parallel legs 5 and a connecting web portion 6, said legs having therein adjacent their free ends alining openings 7 in which are fixedv pivot pins 8. Formed integrally with the web 6 and extending therefrom at right angles to and in the plane of the block is a threaded stem 9 equipped at its outer end with a handle 10. Mounted between the legs 5 of the block at each side of the web 6 and pivotally supported upon the corresponding pin 8 is a jaw 11 provided outwardly of the block with a working face 12 and inwardly thereof with an extension 13 the inner face 14 of which diverges with respect to the stem 9. These Specification of kLetters Patent.

Application filed July 13, 1917. Seria1 No. 180,365.

jaws 11 are adjustable on their pivots to move their working faces toward and away from each other as is readily understood, and are so adjusted by means of a thumb nut 15 which is threaded for longitudinal movement `on the stem 9 and provided with a tapered extension 1G movable between the divergent faces of the extensions 13 of the jaws to spread the same as clearly illustrated in Fig. 2.

The working faces 12 of the jaws 11 are normally urged laway from each other by means of coil springs 16 which are mounted in recesses 17 provided in the web 6 of the block and bear against the inner faces of the jaws outwardly of their pivots, the jaws having their inner face cut away at this point as indicated at 18 in order to properly seat the spring.

l/Vhat I claim isz- 1. An adjustable alligator wrench comprising an integral H-shaped block having an integral threaded stem extending from the web thereof in la plane parallel to and between the arms of the block and at right angles to the extent of the latter, a handle on the free end of the stem, a nut threaded on the stem and having a rounded tapered extension toward the block, oppositely tapered jaws pivoted intermediately of their ends, between the opposed arms of the block adjacent to the extremities thereof at either side of the web and having converging inner faces adjacent to the stem for engagement bv the nut so as to move the opposite faces into clamping relation, said web having opposed recesses facing the jaws and the jaws having their inner faces cut away intermediately throughout the web to accommodate the latter and springs seated in said'recesses and engaging the jaws at the cut-away portions thereof.

Q. An adjustable alligator wrench comprising an integral H-shaped block having an integral threaded stem extendingl from the web thereof in a plane parallel to and between the arms of the block and at right angles to the extent of the latter, a handle on the free end of the stem, a nut threaded on the stem and having a rounded tapered extension toward ,the block, oppositely tapered jaws pivoted intermediately of their wardly of the pivots of the jaws to normally 10 ends, between the opposed arms of the block spread the latter.
